Subject: [PATCH] efinet: Add DHCP proxy support
|
|
|
b71686 |
|
|
|
b71686 |
If a proxyDHCP configuration is used, the server name, server IP and boot
|
|
|
b71686 |
file values should be taken from the DHCP proxy offer instead of the DHCP
|
|
|
b71686 |
server ack packet. Currently that case is not handled, add support for it.
|
|
